How it works

Every ripple is a circular wavefront expanding from its drop point. At any point on the pond, the surface height is the sum (superposition) of every active ripple's contribution:

h(x,y,t) = Σ A0·e^(−decay·age) · sin(k·d − ω·age) · env(d − v·age)

d   = distance from drop point
age = time since that ripple spawned
env = Gaussian ring that keeps the visible
      wavefront a thin expanding band

Where two wavefronts overlap, their heights simply add: crest-on-crest builds a taller peak, crest-on-trough cancels toward flat water — the same constructive/destructive interference the 3D version renders as mesh displacement, computed here on a coarse grid and painted as brightness (crest = bright, trough = dark).

bright = crest · dark = trough
